JUNOSe 11.1.x BGP and MPLS Configuration Guide
ASBR 2 receives MPLS frames with label 44 (the in label) from ASBR 3 and sends
MPLS frames with label 16 (the out label) to PE 1.
The inter-AS next hop shows label 44 as the label advertised to inter-AS peer ASBR 3.
Label 44 was generated for the indirect next hop PE router/label pair, 10.2.2.2 (PE 1)
and 16. Indirect next hop 1.1.1.1 is for the MP-IBGP peering between PE 1 (loopback
address 1.1.1.1) and ASBR 2. Indirect next hop 10.5.5.5 is ASBR 3.
